Hi, I am running leopard 10.5.2 on a 17" hi-res SR MBP. Sometimes I notice that a part of a line or two of text will become bolded and/or run into another line of text making it hard to read. Scrolling up or down to remove the offending line from visibility, and then scrolling back usually fixes it, but it is a nuisance. I have come across this problem using iChat (most common) and Firefox. Any ideas how to fix this?
